THE VELOCITY RATIO OF A MACHINE IS 5 AND ITS EFFICIENCY IS 75%. WHAT EFFORT WOULD BE NEEDED TO LIFT A LOAD OF 150N WITH THE MACHINE
A. 20N B. 30N C. 40N ✓ D. 50N The answer to the question is: C. 40N To calculate the effort needed to lift a load using a machine, we can use the formula: Efficiency = (Actual Mechanical Advantage / Velocity Ratio)…
A TRAIN WITH AN INITIAL VELOCITY OF 20MS-1 IS SUBJECTED TO A UNIFORM DECELERATION OF 2MS-2. THE TIME REQUIRED TO BRING THE TRAIN TO A COMPLETE HALT IS
A. 40s B. 10s ✓ C. 20s D. 5s The answer to the question is: B. 10s To find the time required to bring the train to a complete halt, we can use the equations of motion. The equation that relates initial…
COMPREHENSIVE OVERVIEW OF NERVE CONDUCTION VELOCITY AND ELECTROMYOGRAPHY TESTS
Nerve Conduction Velocity (NCV) and Electromyography (EMG) tests are diagnostic tools used to evaluate the functioning of the nervous system, particularly the peripheral nervous system (PNS). These tests are essential in identifying various neurological disorders and determining the appropriate course…
